SPECIFICATION forming part of Letters Patent No. 636,173, dated October 31, 18991 Application filed April 23, 1898. Serial No. 678,651. (No model.) i

To all whom it may concern.-

Be it known that I, JOH M. PHILLIPS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Car-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to car-wheels, and has for its object the provision of means for effectually lubricating the wheel by means of afiuid lubricating medium carriedin a cavity formed in the wheel adjacent to the hub of the same.

My invention consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawings, Figure 1 is a side elevation of my improved wheel.- Figs. 2 and 4 are vertical transverse sectional views, and. Fig. 3 is a vertical sectional view on the line 13 m of Fig. 2.

A designates the rim of the wheel, B B the spokes of the same, and O the hub, the rim, spokes, and hub being cast in one piece. On opposite sides of the hub and between two of the spokes B B are formed cavities D D, which communicate with one another by channels E E, which are concentric with the central opening F of the hub, and the said central opening of the hub, which receives the axle, communicates with the cavities D D by openings G G. One of the cavities, D, is formed with a hole I for the introduction of oil into the cavity, and this hole is normally closed by means of an elliptic plate K, which is secured to the face of the wheel by means of a malleable rivet k, that is cast into the wheel to one side of the hole I and has ahead hammered up, so as to secure the plate K in position, while allowing the same to rotate. A groove M is formed in the face of the Wheel adjacent to the rivet 7c, and within this groove an arched spring m is placed previously to fixing the rotary plate K in position, the purpose of this spring being to bear against the plate with sul'ficient force to prevent it from rotating accidentally and hold it tightly against the hole I to prevent oil from escap ing or dust from entering the oil-box. In the other cavity D a screw-threaded hole N isformed, through which absorbent material 0 is introduced, so as to entirely fill this cavity, and after theintroduction of this absorbent material, which maybe cotton-waste, the hole N is closed by a screw-plug P.

WVhen it is desired to supply the wheel with lubricating material, such as oil, the plate K is turned around until the oil-hole in the face of the box is exposed. The oil is then poured into the cavity D, and from thence finds its way to the cavity D through the channels E E, and is absorbed by the material 0 therein. If any excess of oil should be fed to the cavity D, it will pass to and fro through the channels E E until the natural consumption of the oil and the slight exudation between the hub and axle exhaust the oil from the absorbent material 0 to such an extent that it will take up the free oil. The lubrication of the axle is accomplished by the passage of the oil from the absorbent material 0 through the openings G G.

Fromthe above description it will be seen that the material serves as a reservoir to hold the lubricating fluid, which will be fed to the axlegradually and accordingly as it is needed, and the presence of this absorbent material prevents surplus oil, if there should be any, from flowing around or churning in the cavities of the wheel and greatly lessens the liability to loss of oil that ensues where theoil is allowed to run around in an unpacked cavity. The oil-hole I in the cavity D is, it will be observed, located about at the center of the cavity, and hence the surplus oil in running around the cavities of the wheel does not flow over this oil-hole, and hence there is no liability of leakage at that point.

Having described my invention, I claim- In a car-wheel the combination with the rim A, the spokes B, B, and the hub F, of the lubricant-reservoirs D, D, formed integral with the spokes and located on opposite sides of the hub, and having concentric communicating channels, the reservoir D, being provided with an opening for the reception of lubricating material and a revolving plate K, In testimony whereof I have afiixed my sig= for closing said opening after the lubricating nature in presence of two Witnesses. material has been introduced and the other T 7 reservoir having an opening for the introduo- JOHL PHILLIPS 5 tion of packing material and a screw-plug P, \Vitnesses:
